The Experimental Study Of The Model Of Anti-Seismic Performance And Shear-Carrying Capacity Of FRP Intensified Masonry Wall

Masonry structure is a kind of structure which has walls and pillars as the main load bearingelements which are made of blocks and sand pulps, having been a traditional construction in ourcountry and is an indispensible part of Chinese culture. Along with the raising tenure of use andlevel of fortification against earthquakes, the strengthening and maintenance of the masonrystructure has reaching an increasingly prominence. In recent years, new materials and structuresof new styles have been springing up with the development of the national economy. SinceChina is at the initial stage of socialism, which is a special stage, along with the developing ofnew forms of construction, strengthening work of existing structures must be done well,especially the masonry structures.Since FRP material could be obtained almost unlimitedly and possesses incomparable andstable characteristics. It could lower the cost by raising the technical level. FRP has won a widepopularity in the strengthening work of civil engineering. In recent years, FRP has been usedconsiderably with a trend into the civil area. Currently, FRP is the most widely used techniquesin civil engineering home and abroad. This papers purports to analyze the superiority of FRPstrengthening techniques by systematically studying the research status of FRP technique homeand abroad. Based on the former experiment, it raises an insightful idea with regard to FRPstrengthening. The main contents are as follow:1. A summary and comparison of methods of FRP material’s shearing resistance andstrengthening, analyzed the contributing factors in influencing shear capacity of the wall body.2. By analyzing the load-deformation hysteresis curve, skeleton curve and rigiditydegeneration curve, it evaluated influences of earthquake resistance performance throughadopting different material and different ways of strengthening the wall body; analyzed thedestruction forms and strengthening principles and compared it with the strengthened masonrypieces. Studies the earthquake resistance performance of the masonry after it is strengthened byFRP. The research shows that the glued CFRP strengthened masonry wall body would notablyraised its earthquake resistance performance.3. In the part of finite element analysis the methods of reinforcement in the test aresimulated, and there is certain error between the results of simulation and that of test. Althoughthere is calculating error, the results of finite element analysis can study stress nature of wallqualitatively. 4. Based on the data collected from former experiment, raise the formula calculating theshear capacity of FRP oblique glued masonry wall piece. By comparing the calculated resultsand the experimental results, it is shown that the formula adopted in this paper is safe enough toconduct engineering design.
